Abstract

The utility model discloses a self-excited oscillation precast beam pedestal, comprising pedestal concrete, wherein a plurality of preserved grooves are formed in the top end of the pedestal concrete; a pedestal steel plate is paved on the grooves; hollow steel pipes are welded on the lower end of the pedestal steel plate and are located in the preserved grooves; vibrating spears are inserted into the hollow steel pipes; a side template is arranged above the pedestal steel plate; and concrete is poured inside an upper template on the pedestal steel plate. According to the self-excited oscillation precast beam pedestal, one or a plurality of hollow steel pipe(s) is/are welded on the lower part of a pedestal bottom template according to the width of the pedestal and is/are taken as inserting holes of the vibrating spears; when the concrete is poured, the vibrating spears are inserted from the steel pipes; the bottom template is vibrated under the drive of the vibrating spears, and the vibrating spears are drawn and pulled to adjust the positions of the vibrating spears along with the pouring progress, so that each position can be guaranteed to be vibrated and compacted; and not only is the problem that the precast beam baseplate is not easily vibrated solved, but also the investment is small, and the operation is convenient.

Description

A kind of self-vibration formula precast beam pedestal
Technical field:
The utility model relates to building engineering field, relates in particular to a kind of self-vibration formula precast beam pedestal.
Background technology:
Domestic prior art precast beam adopts fixed base more, and building underplate concrete needs internal vibration from the top down, because reinforcing bar is intensive, vibrating spear is difficult to insert, operating personnel's workload is big, inserts spacing, the quality of vibrating can't guarantee, causes the underplate concrete leakiness of vibrating easily.Therefore imagination provides a kind of equipment to solve this problem.
The utility model content:
The purpose of this utility model just provides a kind of self-vibration formula precast beam pedestal, solve domestic prior art precast beam and adopt fixed base more, build underplate concrete and need internal vibration from the top down, because reinforcing bar is intensive, vibrating spear is difficult to insert, operating personnel's workload is big, inserts spacing, the quality of vibrating can't guarantee, causes underplate concrete uncompacted problem of vibrating easily.
The technical solution adopted in the utility model is:
A kind of self-vibration formula precast beam pedestal, comprise the pedestal concrete: pedestal concrete top has some reservation grooves, upper berth base steel plate, pre-buried hollow steel tube in reserving groove, and be welded into integral body with the base steel plate; During concreting, in hollow steel tube, insert vibrating head.
The vibrating head jack is reserved in described pedestal concrete below, and jack leads to hollow steel tube, during concreting, vibrating head inserts in pre-buried jack, drive the vibration of base steel plate by vibrating head, and adjust vibrating spear with building the progress pull, the realization underplate concrete is made firm by ramming closely knit.
Side form is installed in described base steel plate top, in the side form of concreting on the base steel plate.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is by welding one or more (determining according to the pedestal width) hollow steel tube in pedestal bed die bottom, as the vibrating spear jack, during concreting, vibrating spear inserts in steel pipe, drive the bed die vibration by vibrating spear, and with building progress pull adjustment vibrating spear position, guarantee each position vibration compacting.Not only overcome the vibrate problem of difficulty of precast beam base plate, and fund input is little, easy to operate.
Description of drawings:
Accompanying drawing 1 is the utility model pedestal drawing in side sectional elevation;
Accompanying drawing 2 is the utility model pedestal longitudinal plan;
Accompanying drawing 3 is the utility model construction schematic diagram.
The specific embodiment:
Below in conjunction with accompanying drawing, be described in further detail by the utility model of embodiment:
A kind of self-vibration formula precast beam pedestal, comprise pedestal concrete 4: pedestal concrete 4 tops have some reservation grooves 3, reserve groove 3 upper ends base steel plate 2 is installed, the lower end of base steel plate 2 is welded with hollow steel tube 1, hollow steel tube 1 is positioned at reserves groove 3, is inserted with vibrating head 5 in the hollow steel tube 1; Side form 7 is installed in base steel plate 2 tops, and concrete 6 is cast in the side form on the base steel plate.
When constructing pedestal concrete 4, reserve 10 * 8cm groove 3 by the position of design, provide free space for Φ 57 * 3.5 steel pipes 1 being installed and being vibrated.Groove 3 is apart from pedestal limit 20cm, spacing 40cm each other.Steel pipe 1 is welded into integral body with base steel plate 2, guarantees that vibrating head 5 vibrations are delivered on the base steel plate 2.Base steel plate 2 is fixed on the pedestal concrete 4 by pre-buried muscle.
Insert in Φ 57 * 3.5 steel pipes 1 the pipe center contact from two ends with Φ 50 vibrating heads 5 before the concreting.When building underplate concrete, start vibrating head 5, drive 2 vibrations of bed die steel plate, reach the effect of vibration compacting.
Concrete implementation step:
A, build pedestal, Φ 57 * 3.5 steel pipe 1 and bed dies are installed;
B, insert vibrating head 5 before building, each hole is respectively inserted one from two ends, in center contact;
C, concreting 6 start vibrating head 5, and vibrating head 5 moves synchronously with the concreting position and outwards extracts.
D, extract vibrating spear 5 and build web concrete.
Above-described embodiment only is preferred implementation of the present utility model, and in addition, the utility model can also have other implementations.Need to prove that under the prerequisite that does not break away from the utility model design, any apparent improvement and modification all should fall within the protection domain of the present utility model.
